About thredUP

In 2009, thredUP set out to make used clothes the new normal and create a more sustainable future for fashion. The company designed a modern resale experience that took the work and risk out of thrift, and converted a generation of secondhand skeptics to fans. Sellers send clothes directly to thredUP by the bagful, and buyers shop quality-checked items from over 35,000 brands at steep discounts. To power this marketplace, thredUP built an infrastructure that has recirculated 100 million unique garments via proprietary technology, data and logistics. thredUP most recently expanded its platform with Resale-as-a-Service (RaaS) to power resale for the world’s leading fashion brands. As a circular fashion pioneer, thredUP is reducing fashion’s impact on the planet and unlocking economic value for consumers and brands alike.

At thredUP, we’re working to revolutionize the clothing industry and we're looking for a curious and creative Data Scientist to help manage our complex multi-sided marketplace.

  • Develop the algorithms and data strategy that power search and discovery, allowing buyers to seamlessly find items they love in our vast assortment
  • Develop rigorous forecasting systems to bring predictability to our planning around inventory growth and economics
  • Create mathematical representations of the flow of items into and out of our marketplace
  • Drive the strategy for promotions, merchandising campaigns, and sales, and investigate their effect on inventory and buyer mix

  • Advanced knowledge of SQL and Python, and experience writing code in a collaborative environment
  • Prior experience working with marketplaces and/or a relevant background in economics or operations research is a plus
